Rated 4.8 out of 5 by 86 reviewers.
Rated 5 out of 5 by Fantastic Stepping Stone As You Bring Your Kitties to No-Grain ! We rescued ferals in our general neighborhood for years. We would graduate them from the most tasty yet least pricey grain-laden (because we were not educated in feline nutrition) kibble to this brand once they decided we had finally tamed down enough for them to live with us. As applicable for their age, they, eventually had this particular kibble in their bowl. It is their early years comfort food. They don't eat much of it anymore but do like having it available. They sort of treat it like a granola bar that is already crumbled up for them, though the hard round pellets do offer them a challenge. They do have to slow down when they eat it or they end up tossing their cookies. By the way, this brand also offers a no grain kibble. Just saying, had I a do over opportunity, I would have gone with the no grain right from the start. And, yes, most likely, have chosen this particular brand. Enjoy! Love Those Felines of Yours! You are All Worthy ! February 13, 2015

Rated 5 out of 5 by As always, Science Diet is great for my animals Got the Science Diet and started to feed it to my cats--the immediate improvement in their appearance and health was magnificent! The cats are doing better and are eating with much enthusiasm!! July 27, 2016
Rated 5 out of 5 by convenient fast efficient service good price My new kitty loves Science diet in cans and the dry. My vet recommended the basic wet and a few sprinkles of the dry. July 8, 2016
Rated 2 out of 5 by Science Diet Optimal Care for Cats The only reason that I provide a small amount of this product is that I was a feral cat person - many years ago I started using this product. A few of the remaining originally trapped and semi-tamed cats are still living and need their "fix" of junk food. I generally feed Taste of the Wild Dry and consider it to have a better grade of ingredients. June 20, 2016
Rated 5 out of 5 by Great product at a great price A great product at a great price. They pack it neatly and it arrives in under a week, usually withing 2 days of ordering except during holidays where there is often a short delay. June 25, 2016

Rated 5 out of 5 by My Kitties LOVE this food! I recently switched my kitties to Hill's Science Diet Adult Optimal Care Chicken Recipe Dry Cat Food. They all had been eating the Longevity recipe. My two older cats passed away, so I wanted to feed my 5 younger kitties an age appropriate food. They all see to be doing well with it. I'm weaning them off the other slower, so as not to cause any IG issues which can happen if you just switch over to the new food. March 28, 2016
Rated 5 out of 5 by Highly Recommended! This cat food stopped my cats from peeing everywhere and also made all the short hair cats coat just beautiful. I recommend it to everyone I know who has cats. Well worth the extra cost. March 20, 2016
Rated 5 out of 5 by good brand and cats like it These pellets are small enough that cats with eating problems are able to eat without problems. It also works for my older kittens. They like the flavor and eat it very well. March 10, 2016

Rated 5 out of 5 by Wonderful cat food I have fed this to my cats (previous one) and new kitty and they love it. Most vets carry it and it is excellent. My kitty loves it. February 23, 2016
Rated 5 out of 5 by good product and price We have fed this dry cat food (in addition to wet) for a long time. We were glad to find it on chewey.com for a little cheaper than our local store, and we don't have to haul it home! Love that! February 18, 2016
Rated 3 out of 5 by My cats liked it but didn't love it Pretty good but wellness better. I mixed the two and they really liked it better. February 4, 2016
Rated 5 out of 5 by An absolutely fantastic product I breed Siamese cats, three of which have always had chronic diarrhea. Recently I was given a Bengal who started having diarrhea all over my apartment up to 6 times a day. My vet suggested that the food I fed my cats might be the problem. I decided to change to Science Diet but expected my food bill to skyrocket. Instead, the cats eat less, there is less solid waste in the litter boxes, all diarrhea has stopped and my cats are more playful and healthy. Using Science Diet with my nine cats actually cut my food bill by $30 per month and has benefitted my cat's overall health tremendously. I highly recommend this product. January 13, 2015
Rated 5 out of 5 by Cat likes this flavor. She is extremely on target with what she favors and what she doesn't. The cat enthusiastically anticipates dining on this cat food. She licks her chops and really does enjoy this cat food. January 18, 2016
Rated 1 out of 5 by Not happy :( My cat Clara who's never been sick vomited all over the house after a meal of this! I waited two days and tried again. Same thing! I'm stuck with 17.5 pound bag of expensive cat food I can't use. NOT A HAPPY SALE! December 17, 2015
Rated 5 out of 5 by Good product. Cats love it. This has been my go-to kibble for years now. My cats all love it. Their coats are nice and shiny and they are healthy. I have added in other kibble options in other bowls, but they always go to this one more. December 8, 2015
Rated 5 out of 5 by Great food, price and shipping. This is a wonderful and nutritious food for the cats. The price is great and the shipping fast. The speedy service is much appreciated. December 15, 2015
